This newly discovered species is anything but new. It's a living fossil, having remained unchanged for 120 million years.
"Since the days of the T. rex, few animals have evolved into such numbers and filled such diverse habitats as ants. Now, scientists say they have uncovered a “living fossil” among the picnic spoilers – a tiny, blind ant whose species appears to be what the team calls “the sole surviving representative” of some of the first ants, which are thought to have evolved from wasp ancestors 120 million years ago."
